Corrosive chemicals and solvents can contaminate signal conductors causing intermittent signals and eventually destroy the sensor housing, connector, and cabling. In industrial environments, the sensor housing should be built of chlorine resistant, 316L stainless steel. Teflon®, Tefzel®, and Viton® connector and cabling materials should also be used due to their strong chemical resistance at high temperatures. Neoprene and polyurethane may be acceptable in benign environments.
